Application filed May 20,

the inside of the room or building, and has for its object to provide an improved constructional form and combination of sash and frame.

The invention will be moreparticularly described by the aid of the accompanying drawings wherein,

Fig. 1 is a front elevation of a window frame with sashes showing the invention applied.

Fig. 2 is a sectional side view showing the bottom sash turned inwards.

. Fig. 3 is a sectional plan view on the line 33 of Fig. 1. v

Fig. 4 is a view corresponding to Fig. 2 but with both sashes turned.

Fig. 5 is a sectional elevation of one side of a window frame showing a modified form of parting beading.

Fig. 6 shows the trunnion plate in front, side and plan view.

Fig. 7 is a front elevation of a modified form of trunnion and Fig. 8 is a side view of Fig. 7, while Fig. 9 is a view corresponding to Fig. 2, but with the hinged members folded inwards but with the sashes in normal position.

According to the invention the sashes, a, 6 (upper and lower respectively) are made of the conventional or other convenient form 'nion c and hes within the before-mentioned but on each side and about midway in their length each sash is provided with a short trunnion 0 preferably carried by a metal plate d let into the wood and formed with a flange d on one side to receive screws or other securing means.

Said flange d in practice is preferably arranged to normally lie on the outside edge of the window sash and the arrangement is such that when the securing means are released the sash can be bodily removed by tilting the same clear of the trunnion plate d.

Specification of Letters Patent.

1920. Serial No. 382,934.

The trunnion c on the opposite side of the sash may be a fixture and where the proportions of the window are such as to allow the trunnions to leave the grooves in the frame, hereinafter explained, the trunnions on both sides may be fixtures as illustrated in Figs. and 8.

, The trunnions c of the outside sash a, slide in grooves 6 formed in the usual vertical runways of the window frame 7', said grooves Patented Apr. ill, 1922. v

extending from the sash cord pulley g to within a short distance above the normal position of the trunnions on the bottom sash. The usual outer and inner beading h and i and parting stripping 2' respectively are pro vided to form additional guides for said" sashes a and Z) the outside beading h descending almost to the bottom of the groove Z while the inner or middle heading 2 is shorter, i. e. lower part is removable, to allow the sash a to be swung inwards on its trunnions as seen in Fig. 4:. I

The uppersash a is provided at each side with a strip i normally alined with and substantially forming an extension of the adjacent parting strip '11.

To the outside of the window frame at the bottom thereof, and one on each side are two strips of wood 25 hinged to the frame adapted to be swung into the position shown in Fig. 3 so that the inner edges t complete the grooves in which the inner sash 2) slides and the top end constitutes a stop to limit the downward movement of the top sash a. The inner edges 6 of the strip I? lie in the grooves formed in the sash b to accomodate the inner or parting beads 1;.

Alternatively the inner or parting bead 2' may be pivotally connected to the window framing at i as seen in Fig. 5 so that it can be moved out of the path of the swinging sashes as indicated in dotted lines.

The sash cord j is attached to the trungroove 6, the pulley 9 being arranged to suit.

' V The inner sash b is also provided with the sash cord is. attached by means'of the hooks s.

It will now be seen that the sashes can be raised and lowered in the usual manner and when it is desired to swing the sashes inwards to'allow access to the exterior of the glass the bottom sash b is first raised and the strips it turned outwardly as indicated in dotted lines in Fig. 8, and the sash is then lowered to a position just clear of the recess m. Upon the hinged rails 11' being turned outwardly the bottom sash b' can be swung about the trunnions to the position shown in Fig. 2 with the outside of the pane on top in a convenientposition for cleaning. It is then returned into position in line with the grooves and the top sash a lowered until the trunnions come to rest at the end of the grooves 0. Both sashes are then turned to the position shown in 'Fig. 4, the outside of the window pane of the top sash then being uppermost and in the cleaning position.

To return the sashes to the normal position they are swung back into line with the respective slide ways. "The hinged beads 92 are then turned back into position and both sashes raised'to the top of the window frame. The outer strips t are then turned into position across the inside of the frame and the bottom sash b lowered'and the window fastened by the catch 0 in the usual manner. When it is desired to have the top sash part open itis lowered on to the strips t which form a convenient stop.

In the case of the pivotally mounted parting bead z" the bottom sash is raised and said head pushed in when it is desired to turn the sashes inwards.

What I claim is v A window of the kind referred to comprising sashes adapted toslide up and down for opening and closing purposes, and a trunnion located substantially midway along the length of each sashand on each side of p the same, in combination with a window frame having grooves to receive the trim-f nions, thelower end-of said grooves 'constituting abutments about which the sashes pivot, theoutside grooves being shorter than the inside groove so that both sashes can be swung inwards, and sash cords connected to the sashes about the pivot centres, the

inner, outer and parting headings of the frame being formed with gaps to allow the sashes to swivel, the gap in the inner beading being closed by a hinged'section, together with hinged members at the rear of said window frame each adapted to form one side of a guiding groove for the lower sash and a stop forthe top sash, substantially. as described. i r

In testimony whereof I have signed my name to this specification.
